Two-stage Compression Double Screw Air Compressor, screw rotor adopts a two-stage compression engine, is to use two groups of size is not consistent, reasonable distribution of pressure, lowering the pressure level at each level compression ratio. Reduce the leakage and improve the capacity, reduce the bearing load, improve the bearing life, prolong the life of the host. The inlet of the main engine adopts the axial inlet, and the intake noise is reduced. Direct drive, high efficiency, low vibration and low noise.

Features:

  • Air End

    Double stage compression compared to single-stage compression,the two compression tends to the most provincial power of the isothermal compression,from the principle,the two-stage compression energy saving 5~8% than single stage.

    Won the award of Level 1 energy Efficiency Grade Certification.
    Compared with Level 2 Energy Efficiency GradeSave 10%-15% energy.
    Compared with Level 3 Energy Efficiency GradeSave 20%-30% energy.

  • Motor

    a)the use of energy-efficient motor,F grade insulation grade,high protection motor,with imported SKF bearings.
    b)the capacity of the motor is increased by 1.2,so as to ensure that under the condition of various weather conditions,the load can be loaded without fault operation.Control panel LCD HD touch monitor,PLC control ,Human menu interface design.
    Can display multi line operation parameters,historical records Simple operation,inquiry ,convenient maintenance.

  • High Efficient Separation of Oil and Gas System

    The oil content of the compressed air of the outlet is only 2ppm by using the three stage method(cyclone separation method,sedimentation separation method and the fine filtration method)

  • Low Noise Design

    A)selection of large diameter,low speed of the low noise fan: provide large air quantity can effectively reduce the fan noise.B)totally enclosed mute type design,accord with international working noise standard.
    B)Totally enclosed mute type design,accord with international working noise standard.

    Two-stage air end

    1. Two-stage compression,the gas is compressed from 1 bar to 3 bar and cooled down then compressed from 3 bar to 7/8bar.
    2. Isothermal compression, The two-stage compression compresses the gas from normal pressure to about 0.2mpa, cools it first, and then after it is compressed to the rated pressure and cooled by the after-cooler, the change of thermal expansion and cold contraction is small, improving the efficiency.
    3. Low compression ratio, greatly reduced reflux leakage, screw host output flow is improved;the compression heat generated in the compression process will be reduced, and the temperature rise in the compression chamber will be low, which can improve the volume efficiency of the compressed air.
